USS Tusk (SS-426), a Balao-class submarine, was the only ship of the United States Navy to be named for the tusk, an alternate name for the cusk, a large edible saltwater fish related to the cod. Her keel was laid down on 23 August 1943 at Philadelphia, Pennsylvania, by the Cramp Shipbuilding Company. She was launched on 8 July 1945 sponsored by Mrs.CarolynParkMills, and commissioned on 11 April 1946 with CommanderRaymond A. Moore in command...
https://en.wikipedia.org/wiki/Balao-class_submarine
The Balao class was a successful design of United States Navy submarine used during World War II, and with 122 units built, the largest class of submarines in the United States Navy. An improvement on the earlier Gato class, the boats had slight internal differences. The most significant improvement was the use of thicker, higher yield strength steel in the pressure hull skins and frames, which increased their test depth to 400 feet (120 m). Tang actually achieved a depth of 612 ft (187 m) during a test dive, and exceeded that test depth when taking on water in the forward torpedo room while evading a destroyer.
Propulsion
The propulsion of the Balao-class submarines was generally similar to that of the preceding Gato-class. Like their predecessors, they were true diesel-electric submarines: their four diesel engines powered electrical generators, and electric motors drove the shafts. There was no direct connection between the main engines and the shafts.
Balao-class submarines received main engines from one of two manufacturers. Fairbanks-Morse supplied Model 38D8-⅛ opposed piston engines, and General Motors' Electro-Motive Diesel division supplied Model 16 V16 engines. Earlier Fairbanks-Morse boats received a 9-cylinder version of the Model 38D8-⅛, while boats from USS Sand Lance (SS-381) onward received 10-cylinder engines. Earlier GM boats received Model 16-248 engines, but beginning with USS Perch (SS-313) Model 16-278A engines were used. In each case, the newer engines had greater displacement than the old, but were rated at the same power; they operated at lower mean effective pressure for greater reliability...
Two manufacturers supplied electric motors for the Balao-class. Elliott Company motors were fitted primarily to boats with Fairbanks-Morse engines. General Electric motors were fitted primarily to boats with General Motors engines, but some Fairbanks-Morse boats received GE motors. Allis-Chalmers motors were to be used in SS-530 through SS-536, but those seven boats were cancelled before even receiving names.
Earlier submarines carried four high-speed electric motors (two per shaft), which had to be fitted with reduction gears to slow their outputs down to an appropriate speed for the shafts. This reduction gearing was very noisy, and made the submarine easier to detect with hydrophones. A handful of late Balao-class submarines received low-speed double armature motors which drove the shafts directly and were much quieter, but this improvement was not universally fitted until the succeeding Tench-class. As the diesel engines were not directly connected to the shafts, the electric motors had to drive the shafts all the time.
The Balao class was successful, and one of its class USS Archer-Fish (SS-311) brought down what remains the largest ship sunk by a submarine, the Japanese aircraft carrier Shinano (59,000 tons).
As of2007 USS Tusk (SS-426), a Balao-class submarine, was one of the last two operational submarines in the world built during World War II. It was transferred to the Republic of China in the early 1970s...

The U.S. Navy traces its origins to the Continental Navy, which was established during the American Revolutionary War and was essentially disbanded as a separate entity shortly thereafter. It played a major role in the American Civil War by blockading the Confederacy and seizing control of its rivers. It played the central role in the World War II defeat of Japan. The 21st century U.S. Navy maintains a sizable global presence, deploying in such areas as East Asia, the Mediterranean, and the Middle East. It is a blue-water navy with the ability to project force onto the littoral regions of the world, engage in forward areas during peacetime, and rapidly respond to regional crises, making it an active player in U.S. foreign and defense policy.

Alan with the U.S. NAVY at DARPA's Tech Expo shows us some tricked up and easy to build SeaPerch ROV subs with GoPro and other cameras for underwater driving fun and learning.
"SeaPerch is an innovative underwater robotics program that equips teachers and students with the resources they need to build an underwater Remotely Operated Vehicle (ROV) in an in-school or out-of-school setting. Students build the ROV from a kit comprised of low-cost, easily accessible parts, following a curriculum that teaches basic engineering and science concepts with a marine engineering theme. The SeaPerch Program provides students with the opportunity to learn about robotics, engineering, science, and mathematics (STEM) while building an underwater ROV as part of a science and engineering technology curriculum. Throughout the project, students will learn engineering concepts, problem solving, teamwork, and technical applications.
Where the name “SeaPerch” came from? We asked the inventor of the original SeaPerch, Mr. Harry Bohm, and he shared the story with us. Mr. Bohm explains that the name SeaPerch came from the USS Perch, a highly decorated World War II U.S. submarine.
USS Perch was one of a new breed of American submarines and was the first to incorporate an early form of air conditioning. She was launched May 9, 1936 by the Electric Boat Company in Groton, CT and was scuttled by her crew in the Java Sea on March 3, 1942 after being severely damaged during a Japanese depth charge attack two days earlier. The crew was captured and sent to a Japanese prisoner of war camp; all but six of the 54 men and five officers onboard returned home after the war.
Her wreckage was discovered in November 2006 by an international team of divers off the coast of Java and was the object of archeological diver exploration. "

The Balao class was successful, and one of its class USS Archer-Fish (SS-311) brought down what remains the largest ship sunk by a submarine, the Japanese aircraft carrier Shinano (59,000 tons).

Alan with the U.S. NAVY at DARPA's Tech Expo shows us some tricked up and easy to build SeaPerch ROV subs with GoPro and other cameras for underwater driving fun and learning.
"SeaPerch is an innovative underwater robotics program that equips teachers and students with the resources they need to build an underwater Remotely Operated Vehicle (ROV) in an in-school or out-of-school setting. Students build the ROV from a kit comprised of low-cost, easily accessible parts, following a curriculum that teaches basic engineering and science concepts with a marine engineering theme. The SeaPerch Program provides students with the opportunity to learn about robotics, engineering, science, and mathematics (STEM) while building an underwater ROV as part of a science and engineering technology curriculum. Throughout the project, students will learn engineering concepts, problem solving, teamwork, and technical applications.
Where the name “SeaPerch” came from? We asked the inventor of the original SeaPerch, Mr. Harry Bohm, and he shared the story with us. Mr. Bohm explains that the name SeaPerch came from the USS Perch, a highly decorated World War II U.S. submarine.
USS Perch was one of a new breed of American submarines and was the first to incorporate an early form of air conditioning. She was launched May 9, 1936 by the Electric Boat Company in Groton, CT and was scuttled by her crew in the Java Sea on March 3, 1942 after being severely damaged during a Japanese depth charge attack two days earlier. The crew was captured and sent to a Japanese prisoner of war camp; all but six of the 54 men and five officers onboard returned home after the war.
Her wreckage was discovered in November 2006 by an international team of divers off the coast of Java and was the object of archeological diver exploration. "

USS Perch in San Diego

APSS-313, the USS Perch is part of a submarine nest tied up to the USS Nereus in San Diego...

"BASIC SUBMARINE SYSTEMS, DESCRIPTION OF THE PRESSURE HULLS, TANKS AND SUPER-STRUCTURE."
The submarine shown at the end of the film is the USSTusk, SS-426, a Balao class submarine which was sold to the Republic of China (Taiwan) in 1973, and, as of 2008, was still in use at KaohsiungNaval Base, under the name Hai Pao, numbered SS-792.
US Navy training film FN-8024b
https://en.wikipedia.org/wiki/USS_Tusk_(SS-426)
USS Tusk (SS-426), a Balao-class submarine, was the only ship of the United States Navy to be named for the tusk, an alternate name for the cusk, a large edible saltwater fish related to the cod. Her keel was laid down on 23 August 1943 at Philadelphia, Pennsylvania, by the Cramp Shipbuilding Company. She was launched on 8 July 1945 sponsored by Mrs.CarolynParkMills, and commissioned on 11 April 1946 with CommanderRaymond A. Moore in command...
https://en.wikipedia.org/wiki/Balao-class_submarine
The Balao class was a successful design of United States Navy submarine used during World War II, and with 122 units built, the largest class of submarines in the United States Navy. An improvement on the earlier Gato class, the boats had slight internal differences. The most significant improvement was the use of thicker, higher yield strength steel in the pressure hull skins and frames, which increased their test depth to 400 feet (120 m). Tang actually achieved a depth of 612 ft (187 m) during a test dive, and exceeded that test depth when taking on water in the forward torpedo room while evading a destroyer.

Allis-Chalmers motors were to be used in SS-530 through SS-536, but those seven boats were cancelled before even receiving names.
Earlier submarines carried four high-speed electric motors (two per shaft), which had to be fitted with reduction gears to slow their outputs down to an appropriate speed for the shafts. This reduction gearing was very noisy, and made the submarine easier to detect with hydrophones. A handful of late Balao-class submarines received low-speed double armature motors which drove the shafts directly and were much quieter, but this improvement was not universally fitted until the succeeding Tench-class. As the diesel engines were not directly connected to the shafts, the electric motors had to drive the shafts all the time.
The Balao class was successful, and one of its class USS Archer-Fish (SS-311) brought down what remains the largest ship sunk by a submarine, the Japanese aircraft carrier Shinano (59,000 tons).
As of2007 USS Tusk (SS-426), a Balao-class submarine, was one of the last two operational submarines in the world built during World War II. It was transferred to the Republic of China in the early 1970s...

In each case, the newer engines had greater displacement than the old, but were rated at the same power; they operated at lower mean effective pressure for greater reliability...
Two manufacturers supplied electric motors for the Balao-class. Elliott Company motors were fitted primarily to boats with Fairbanks-Morse engines. General Electric motors were fitted primarily to boats with General Motors engines, but some Fairbanks-Morse boats received GE motors. Allis-Chalmers motors were to be used in SS-530 through SS-536, but those seven boats were cancelled before even receiving names.
Earlier submarines carried four high-speed electric motors (two per shaft), which had to be fitted with reduction gears to slow their outputs down to an appropriate speed for the shafts. This reduction gearing was very noisy, and made the submarine easier to detect with hydrophones. A handful of late Balao-class submarines received low-speed double armature motors which drove the shafts directly and were much quieter, but this improvement was not universally fitted until the succeeding Tench-class. As the diesel engines were not directly connected to the shafts, the electric motors had to drive the shafts all the time.
The Balao class was successful, and one of its class USS Archer-Fish (SS-311) brought down what remains the largest ship sunk by a submarine, the Japanese aircraft carrier Shinano (59,000 tons).
As of2007 USS Tusk (SS-426), a Balao-class submarine, was one of the last two operational submarines in the world built during World War II. It was transferred to the Republic of China in the early 1970s...

DIY Robot Submarines by the U.S. Navy

Alan with the U.S. NAVY at DARPA's Tech Expo shows us some tricked up and easy to build SeaPerch ROV subs with GoPro and other cameras for underwater driving fun and learning.
"SeaPerch is an innovative underwater robotics program that equips teachers and students with the resources they need to build an underwater Remotely Operated Vehicle (ROV) in an in-school or out-of-school setting. Students build the ROV from a kit comprised of low-cost, easily accessible parts, following a curriculum that teaches basic engineering and science concepts with a marine engineering theme. The SeaPerch Program provides students with the opportunity to learn about robotics, engineering, science, and mathematics (STEM) while building an underwater ROV as part of a science and engineering technology curriculum. Throughout the project, students will learn engineering concepts, problem solving, teamwork, and technical applications.
Where the name “SeaPerch” came from? We asked the inventor of the original SeaPerch, Mr. Harry Bohm, and he shared the story with us. Mr. Bohm explains that the name SeaPerch came from the USS Perch, a highly decorated World War II U.S. submarine.
USS Perch was one of a new breed of American submarines and was the first to incorporate an early form of air conditioning. She was launched May 9, 1936 by the Electric Boat Company in Groton, CT and was scuttled by her crew in the Java Sea on March 3, 1942 after being severely damaged during a Japanese depth charge attack two days earlier. The crew was captured and sent to a Japanese prisoner of war camp; all but six of the 54 men and five officers onboard returned home after the war.
Her wreckage was discovered in November 2006 by an international team of divers off the coast of Java and was the object of archeological diver exploration. "
